DRESSING FOR LETTUCE
Rub the yolks of two hard-boiled eggs to a paste, adding one teaspoon of
salad oil or melted butter, being careful to add only a few drops at a
time. Add one-half teaspoon salt, one-half teaspoon of prepared mustard,
very little pepper, two tablespoons of white sugar. Stir very hard, then
pour in gradually one-half teacup of vinegar.
